1. Förfarande fSr tillverkning av papper, varunder bakvattnet re-cirkuleras och vilket innefattar bildande av en första fiberdispersion 5 inom ett dispergermedium innehällande ett viskositetsmodifierande medel; reducering av fiberkonsistensen inom dispersionen; bildande pa en pappers-tillverkningssil av en fibrös pappersbana av nämnda dispersion med re-ducerad fiberkonsistens under separering och uppsamling av det genom silen passerande dispergermediet som bakvatten och kontinuerlig cirku- 10 lering av bakvattnet fSr att äter användas vid bildande av en efter-fSljande fiberdispersion utan att väsentligen ytterligare mängder av viskositetsmodifierande medel behSver tlllsättas, varvid det viskositets-modifierande medlets koncentration bibehalles väsentligen konstant under hela den kontinuerliga cirkuleringsprocessen, kännetecknat 15 av att fiberdispersionen fSre bildandet av fiberbanan behandlas i syfte att reducera dispergermediets viskositet och att atminetone en del av det uppsamlade bakvattnet behandlas i syfte att Ska bakvattnets viskositet innan detsamma användes vid bildandet av fiberdispersionen.
1 Patentkrav
2. FSrfarande enligt patentkrav 1, kännetecknat av att dispergermediets viskositet kan varieras efter mediets pH-värde, varvid ändringen av viskositeten hos dispergermediet och det uppsamlade bakvattnet genomfSres medelst en lämplig ändring av mediets pH-värde.
3. FSrfarande enligt patentkrav 1 eller 2, kännetecknat av att vid reduceringen av fiberkonsistensen tillsättes dispersionen en ut-spädningslösning, som innehaller det viskositetsmodifierande medlet väsentligen i samma koncentration som dispergermediet med en hSgre viskositet. 30
4. FSrfarande enligt patentkrav 1 eller 2, kännetecknat av att en del av det uppsamlade bakvattnet tillsättes fiberdispersionen fSr att astadkomma nämnda reduktion av fiberkonsistensen utan att det viskositetsmodif ierande mediets koncentration ändras. 35
5. FSrfarande enligt nagot av patentkraven 1-4, kännetecknat av att dispergermediets viskositet reduceras samtidigt med fiberkonsis- II
